Abstract
The utility model discloses an elevator rope slack protecting device, which comprises a safety switch (1), an actuating plate (4) and a rotating shaft (7); the safety switch (1) is arranged on an elevator rope hitch plate (6) through a support component; the actuating plate (4) is arranged on the support component in a rotating way through the rotating shaft (7); the actuating plate (4) comprises a rope hitch push part which is correspondingly matched with the rope hitch (5) and pushed by the rope hitch (5) when an elevator rope is abnormal and the rope hitch (5) rebounds, and a switch trigger part which is correspondingly matched with the safety switch (1) and triggers the safety switch (1) to work when the rope hitch (5) pushes the actuating plate (4) to rotate; when the rope is normal, the switch trigger part keeps a distance from the safety switch (1). The elevator rope slack protecting device is safety and reliable, and can stop an elevator from working upon slack and other danger produced by the breakage or abnormal extension of the elevator rope; and in addition, the elevator rope slack protecting device has simple structure, is convenient to process, has low cost, and is good for promotion.
Description
Technical field
The utility model relates to a kind of fender guard of elevator slack rope.
Background technology
Elevator industry develop rapidly in recent years, people also constantly improve the safety requirements of elevator, when elevator wire rope take place to disconnect or during the steel rope abnormal elongation causes unsafe condition such as loosening, should effectively stop elevator to move under this class situation, this is directly connected to the in-use performance of elevator and passenger's the security of the lives and property.
At present, existing elevator rope creep protection device also exists structure comparatively complicated, processing and manufacturing cost height, and on-the-spot the adjustment installed difficulty, the not high shortcomings of reliability.
The utility model content
The purpose of this utility model is: a kind of fender guard of elevator slack rope is provided, and it is safe and reliable, when elevator wire rope take place to disconnect or during the steel rope abnormal elongation causes unsafe condition such as loosening, can stop elevator to move under this class situation; And simple in structure, processing and fabricating is convenient, and cost is low, is beneficial to popularization.
The technical solution of the utility model is: a kind of fender guard of elevator slack rope, it comprises safety switch, support element, turning cylinder, action plate, described safety switch is installed on the elevator rope hitch plate by support element, action plate is installed on the support element by turning cylinder is rotating, action plate includes: be provided with the fag end corresponding matching, when elevator wire rope takes place to disconnect or the steel rope abnormal elongation, when fag end rebounds under the effect of self spring, the fag end pushing part that meeting is promoted by fag end, and be provided with the safety switch corresponding matching, when fag end pushing action plate rotates, the switch triggering portion that can trigger safety switch and safety switch is moved; When elevator wire rope just often, switch triggering portion and safety switch keep the distance.
Below technique scheme is further described:
Described support element comprises interconnected first supporting plate and second supporting plate, and described safety switch is installed on the rope hitch plate by first supporting plate, and described action plate is installed on second supporting plate by turning cylinder is rotating.
Described action plate is provided with and can forces action plate to the counterweight of rotating away from the direction of safety switch.
Described second supporting plate is provided with the limit movement plate to the restriction site of fag end prescription to rotation.
Connect by fastener between described first supporting plate and second supporting plate.
Described fastener is a screw-nut.
The utility model has the advantages that:
1, the fender guard of elevator slack rope of the present utility model is safe and reliable, when elevator wire rope take place to disconnect or during the steel rope abnormal elongation causes unsafe condition such as loosening, can stop elevator to move under this class situation; And simple in structure, processing and fabricating is convenient, and cost is low, is beneficial to popularization.
2, the fender guard of elevator slack rope of the present utility model, the relative position of the safety switch and first supporting plate, the relative position of first supporting plate and second supporting plate is adjustable, can carry out scene adjustment, assurance function.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model (overlooking).
Wherein: 1 safety switch; 2 first supporting plates; 3 second supporting plates; 4 action plates; 5 fag ends; 6 rope hitch plates; 7 turning cylinders; 8 counterweights.
The specific embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of fender guard of elevator slack rope, it comprises safety switch 1, first supporting plate 2, second supporting plate 3, action plate 4, turning cylinder 7.
When elevator wire rope just often, fag end pushing part and fag end 5 keep the distance, switch triggering portion and safety switch 1 keep the distance.
When elevator wire rope take place to disconnect or the steel rope abnormal elongation, when fag end 5 rebounded under the effect of self spring, the fag end pushing part can be promoted by fag end 5, and promptly action plate 4 is pushed.
When fag end 5 pushing action plates 4 rotated, switch triggering portion can trigger safety switch 1 and make safety switch 1 action.
In the utility model, each several part size, quantity can require to make, install according to reality.
During use, under general state, because the weight of the counterweight 8 of action plate 4 right-hand members, the moving axis 7 that rotates rotates, and the restriction site that is positioned at second supporting plate, 3 right-hand members blocks action plate 4, keeps common state.
When steel rope takes place loosening or disconnects, because load reduces suddenly, fag end 5 bounce-back downwards under the effect of self spring, pushing action plate 4 moving axis 7 that rotates rotates, and triggers safety switch 1 action, realizes relevant actions such as towing machine braking.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned embodiment through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than restriction.In a word, protection domain of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
